Answer:
the stream contains more water and moves faster
Explanation:
Answer:
Net number of sigma bonds = 1
Net number of pi bonds = 2
Overall bond order = 3
Explanation:
Electronic configuration of N2 ia
1s2 2s2 2p3
There is head to head overlap in pz orbital. Thus, there is one sigma bond
Pi bond is formed whenever there is side wise overlapping. Since both px and py undergoes overlapping to form pi bond, there are two pi bonds
Bond order = 0.5 (bonding electron – antibonding electron)
= 0.5 (8-2) = 0.5*6 = 3
Pressure of the Mixture = 101.4 kpa
Pressure of the helium phe = 82.5 kpa
Pressure of CO2 pco2 = 0.4 kpa.
Partial pressure of oxygen = Pressure of the Mixutre - (Pressure of the
helium + Pressure of CO2)
Partial pressure of oxygen = 101.4 - 82.5 - 0.4
Partial pressure of oxygen = 18.5 kPa
It's an alkali metal so one, they sit on the very first of the column in the periodic table :DDDD
Answer:
E = 3.035× 10-¹⁹J = 1.9eV
f = 4.58 × 10¹⁴Hz
Explanation:
wavelength = 6.55 × 10-⁷m
c = 3 × 10⁸m/s
f = ?
E = ?
a) f = c/wavelength
f = 3 × 10⁸/6.55 × 10-⁷
f = 4.58 × 10¹⁴Hz
b) E = hc/wavelength
E = 6.626×10-³⁴ × 3 × 10⁸/ 6.55 × 10-⁷
E = 3.035 × 10-¹⁹J
1ev = 1.6 × 10-¹⁹J
Therefore E = 3.035/1.6 = 1.9eV
